众所周知,数学是一门抽象而严谨的学科。在教学中,如果教师只是一味传授理论知识,要求学生强记熟背,那么学生学起来就会显得力不从心,教学效果只会事倍功半。俗话说:实践出真知。在教学中让学生积极参与动手操作,不但能培养学生具体的操作技能,而且对于学生思维能力、创造才能的发展都有着重要的意义。 As we all know, mathematics is an abstract and rigorous discipline. In teaching, if teachers simply impart theoretical knowledge, require students to remember well, then students will find it hard to learn, teaching effectiveness will only be more effective. As the saying goes: practice out of truth. In teaching students to actively participate in hands-on operation, not only to develop students’ specific skills, but also for the students thinking ability, the development of creative ability are of great significance.
